A veto override is Congress's power to pass a bill into law despite the president's veto, requiring a two-thirds supermajority vote in both the House and the Senate. It's a core legislative check on executive power tested in AP Gov Topic 2.5 (Checks on the Presidency).
A veto override is what happens when Congress refuses to take no for an answer. The president vetoes a bill, sends it back to Congress with objections, and Congress votes again. If two-thirds of the House AND two-thirds of the Senate vote yes, the bill becomes law without the president's signature.
That two-thirds threshold is the whole story. A simple majority got the bill to the president's desk in the first place, so requiring a supermajority to override means Congress needs much broader agreement, almost always bipartisan, to beat a veto. That's why overrides are rare. The Framers built it this way on purpose. The president gets a real check on Congress (the veto), but Congress keeps the final word on legislation if it can unite behind a bill. Neither branch gets to win alone.
Veto overrides live in Unit 2: Interactions Among Branches of Government, specifically Topic 2.5: Checks on the Presidency, supporting learning objective 2.5.A, which asks you to explain how the president's agenda creates tension and confrontation with Congress. The veto-and-override exchange is that tension in its purest form. The president blocks Congress's agenda; Congress can strike back, but only with overwhelming numbers.
It also connects back to the foundational logic of separation of powers and checks and balances from Unit 1 (think Federalist No. 51 and 'ambition must be made to counteract ambition'). When an FRQ asks you for a way Congress can check the executive branch, veto override is one of the cleanest, most concrete answers you can give.

Presidential Veto (Unit 2)
You can't have an override without a veto first. The veto is the president's check on Congress; the override is Congress's check on the check. Knowing both halves lets you explain how a single bill can bounce between branches.
Checks and Balances (Unit 1)
The override is Madison's Federalist 51 logic in action. Each branch gets a weapon against the others, but no weapon is final. The president can stop a majority of Congress, but not a united supermajority.
Supermajority (Unit 2)
The two-thirds requirement is the same kind of high bar used for treaty ratification, constitutional amendments, and removal after impeachment. The pattern is consistent. When the Constitution wants an action to be hard and bipartisan, it demands a supermajority.
Impeachment Process (Unit 2)
Both are congressional checks on the presidency, but they target different things. An override reverses one policy decision; impeachment and removal targets the officeholder. Removal in the Senate also requires a two-thirds vote, so the supermajority logic repeats.
Veto override shows up most often in multiple-choice questions about checks on the presidency, usually alongside Senate confirmation of appointments, the power of the purse, and impeachment. A common stem describes a conflict between the president's agenda and Congress (like a vetoed bill or a contested nominee) and asks which constitutional tool applies. You need to match the tool to the situation, and the override only applies after a regular veto.
No released FRQ has hinged on the term verbatim, but it's a reliable piece of evidence for the Concept Application and Argument Essay questions whenever the prompt involves separation of powers, legislative-executive conflict, or limits on presidential power. The move the exam rewards is being specific. Don't just say 'Congress can check the president.' Say Congress can override a veto with a two-thirds vote in both chambers, and explain why that supermajority makes overrides rare.
Congress can only override a regular veto, where the president formally rejects the bill and returns it. A pocket veto happens when the president simply doesn't sign a bill and Congress adjourns within ten days, so the bill dies. Since there's nothing returned to vote on, a pocket veto cannot be overridden. If an exam question involves Congress adjourning, the override option is off the table.
A veto override lets Congress pass a bill into law over the president's objection with a two-thirds vote in both the House and the Senate.
Overrides are rare because the two-thirds supermajority requirement almost always demands bipartisan support, far more than the simple majority that passed the bill originally.
The override is a direct example of checks and balances, supporting LO 2.5.A on how the president's agenda creates tension with Congress.
A pocket veto cannot be overridden, because the bill is never returned to Congress for a new vote.
On FRQs, the strongest answers name the mechanism precisely, including the two-thirds requirement in both chambers, rather than vaguely saying Congress can 'check' the president.
A veto override is when Congress passes a bill into law despite the president's veto by getting a two-thirds vote in both the House and the Senate. It's a key congressional check on the presidency covered in Topic 2.5 of Unit 2.
No. Congress can only override a regular veto, where the president returns the bill with objections. A pocket veto, where the president ignores a bill while Congress adjourns within ten days, kills the bill with no chance of an override.
Two-thirds of the members voting in each chamber, both the House and the Senate. A two-thirds vote in just one chamber is not enough.
An override reverses a single policy decision by passing a vetoed bill anyway, while impeachment targets the president personally for alleged wrongdoing and can lead to removal from office. Both are congressional checks on the executive, and both involve a two-thirds Senate threshold at some stage, but they answer completely different problems.
Because the two-thirds requirement is a much higher bar than the simple majority needed to pass the bill in the first place. The president's own party usually controls enough seats in at least one chamber to block an override, so successful overrides typically require broad bipartisan agreement.
